  • Note: Some OIML Recommendations are now presented in Adobe Portfolio format. To be able to open these documents in a Windows environment, you must download Adobe Reader DC and save the portfolio to a local directory (rather than opening it directly in your web browser). Alternatively, Foxit Reader is a free utility that can open Adobe Portfolios once they have been saved to a local directory. In a Linux environment, the contents of a Portfolio may be viewed using “Evince”, and then setting the side panel to attachments mode.
